Katie Geoghegan Thespian Troupe 483 supports theatre at Sentinel. This talented and unique group keeps busy throughout the year putting on two all-school plays, performing improvisational theater, putting on the Sadie Hawkins dance, and doing fundraisers to finance theater trips to New York City.  

    All students are encouraged to audition for plays which, in the past, have included Our Town, The Servant of Two Masters, The Curious Savage, and the Miracle Worker. 

    There are many opportunities to participate in theater both on stage and doing technical work such as running lights or sound, building or painting the sets, finding props, or helping with publicity. New membership into Troupe 483 requires 100 hours worth of work on plays and a C average. For more information, contact Katie Geoghegan at
